According to edmunds...

"More than just a straight-line runner, the 2006 Jeep Grand Cherokee SRT8 handles the curves like a sport sedan. Among the handling enhancements are Bilstein shocks and beefy stabilizer bars for the independent front and live-axle rear suspension. A front strut tower brace adds stiffness to the chassis as well as additional street cred.

A stable cornering attitude guided by firm and precise steering show that all areas of performance were given equal weight. Running through the slalom at 63.5 mph, the SRT8 crushes the rear-wheel-drive TrailBlazer SS (60.3 mph) we recently tested and ties the Cayenne Turbo."
